Supply Voltage (Power)

CAUTION
Observe the safety instructions when handling supply voltage. Injury possible.
- 3-pin pluggable screw terminal (24 VDC,
GND, Shield),
- 24 VDC 15 %, I <1 A
±
max
- not electrically separated, GND is electri-
cally connected to GND for switching out-
puts, synchronization and encoder input.
Use shielded cable with a length
< 30 m.
Voltage supply only for measuring devices,
not to be used for drives or similar sources
of impulse interference at the same time.
MICRO-EPSILON recommends using an
optional available power supply unit PS2020
for the controller.
After the supply voltage has been switched on, the Power LED lights up.
5.4.5

RS422

- Differential signals in accordance with EIA-422, electrically isolated from the supply voltage.
- Receiver Rx with a 120 ohm internal terminating resistor.
Terminate the transmitter input (TX)
with 90 ...120 ohm on the evaluation
unit (receiver).
Use a shielded twisted cable. Cable
length less than 30 m.
Connect the ground connections.
i
The pin assignment for the 9-pin D-sub
socket is not standardized.
5.4.6

Ethernet, EtherCAT

Potential-separated RJ 45 standard socket
for connecting the IMC5x00 controller
- to an Ethernet network (PC) or
- the EtherCAT bus system (IN-Port).
Use a shielded Ethernet cable (Cat5E,
patch cable, 2 m, included in the
delivery), overall cable length less
than 100 m to connect controller and
network.
Both LEDs in each of the plug-in connectors
indicate a successful connection and its
activity.
The controller can be configured using
- the web interface, see
- ASCII commands, see
- EtherCAT, see Chap. A
